Product Description:
The MSK070D-0450-NN-S1-UG1-NNNN synchronous servomotor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts drive output into precise rotary motion for machine tools, packaging stations, and handling modules that require repeatable positioning. The unit follows the standard mechanical layout used in this motor line, and its 070 frame size helps it fit compactly into multi-axis gantries. An integrated feedback assembly lets the connected controller close high-resolution position and speed loops without external transducers, which helps save installation space and reduces the number of separate motion components.
For thermal management, the motor relies on natural convection, so no fan or liquid circuit is required at the installation site. The encoder plug uses a rotatable 240° connector, allowing the cable exit angle to be adjusted after the motor is mounted. Position data are exchanged through the Hiperface interface, which carries both incremental and absolute information to the drive. Inside the housing, an optical scanning system provides 128 signal periods per mechanical revolution, giving the controller fine interpolation capability during motion control. Winding code 0450 indicates the stator characteristics used with medium-power IndraDrive inverter modules while supporting moderate thermal rise during continuous duty.
The integrated holding brake is electrically released and provides 23 Nm of static torque, allowing vertical or indexing axes to remain locked when system power is removed. Because the feedback device is single-turn, absolute position information is available within one mechanical revolution, so external referencing is needed when multi-turn tracking is required. The mechanical form factor uses length code D, which provides an extended active stack without changing the 70 mm frame envelope. A plain shaft simplifies coupling to gears or pulleys by avoiding key-seat stress points and supporting uniform clamping with shrink-fit hubs.
